Suppose n is a variable of the type Byte and we wish to put OFF its fourth bit (from right) without disturbing any other bits. Which of the following statements will do this correctly?

int num = 1, z = 5;

if (!(num <= 0))
    Console.WriteLine( ++num + z++ + " " + ++z ); 
else
    Console.WriteLine( --num + z-- + " " + --z ); 

1. >=
2. !=
3. Not
4. <=
5. <>=

1. ++a++;
2. a += 1;
3. a ++ 1;
4. a = a +1;
5. a = +1;

if ((n&16) == 16)
Console.WriteLine("Fourth bit is ON");

if ((n&8) == 8)
Console.WriteLine("Fourth bit is ON");

if ((n ! 8) == 8)
Console.WriteLine("Fourth bit is ON");

if ((n ^ 8) == 8)
Console.WriteLine("Fourth bit is ON");

if ((n ~ 8) == 8)
Console. WriteLine("Fourth bit is ON");

byte b1 = 0xF7;
byte b2 = 0xAB;
byte temp;
temp = (byte)(b1 & b2);
Console.Write (temp + " ");
temp = (byte)(b1^b2);
Console.WriteLine(temp);

1. &&
2. ||
3. !
4. Xor
5. %

int a = 10; 
int b = 20;
bool c;
c = !(a > b);

1. There is no error in the code snippet.
2. An error will be reported since ! can work only with an int.
3. A value 1 will be assigned to c.
4. A value True will be assigned to c.
5. A value False will be assigned to c.
